    Company history

  • Why Do We Need Gas Detectors?Risks Associated with Toxic Gases

  • Need for gas detectors (combustible gases)

    We need gas detectors because flammable gas leaks can lead to explosions.

    Criteria set by United Nations’ Globally Harmonized System of Classification and Labelling of Chemicals (GHS)According to the United Nations’ Globally Harmonized System of Classification and Labelling of Chemicals (GHS), a combustible gas (or flammable gas) is defined as follows:

    A combustible or flammable gas is a gas having an explosive (flammable) range when mixed with air under atmospheric conditions of 20°C and standard pressure of 101.3 kPa.

    Gases falling under this definition are further subdivided into the following two categories based on the severity of the associated risk:

    Category 1 (Danger: Extremely flammable gas)Gases capable of igniting at 20°C and standard pressure of 101.3 kPa when occurring in a mixture of 13% or less by volume with air or having an explosive (flammable) range of at least 12% when mixed with air regardless of the lower explosion (flammable) limit

    Category 2 (Warning: Flammable gas)Gases, other than those in Category 1, which are gaseous at 20°C and a standard pressure of 101.3 kPa and have an explosive (flammable) range when mixed with air

  • Need for gas detectors (definition of permissible concentration)

    Definition of permissible concentrationEven when workers are exposed to hazardous substances at work sites, no adverse health effects should emerge as long as the airborne concentration of the hazardous substance remains below the permissible concentration.

    Recommended permissible concentrations have been set by the American Conference of Governmental Industrial Hygienists (ACGIH) and the Japan Society for Occupational Health. We use the ACGIH permissible concentrations.

    Types of permissible concentrations TWA (Time Weighted Average)

    Time Weighted Average refers to time-weighted average concentrations over an 8-hour workday and 40-hour workweek of routine work to which workers may be repeatedly exposed without adverse health effects.

    STEL (Short Term Exposure Limit)Short Term Exposure Limit refers to exposure that does not lead to adverse health effects if each exposure does not exceed 15 minutes, the number of daily exposures does not exceed four, and the exposures are separated by at least one hour.

    C (Ceiling value)Ceiling Value refers to the upper limit that can never be exceeded.

    We need gas detectors because leaks exceeding permissible concentrations can lead to accidents.

    [Background of adoption]Particularly in countries other than Japan, LNG is purchased from multiple suppliers. Use of shale gas and other fuels is expected to increase in the future. Since fluctuations in calorific value affect burner performance significantly, OHC is also installed in the heating furnace to control calorific value.

  • Major Examples of AccidentsPrepared by extracting and processing materials from the Safety at Work Site (Ministry

    of Health, Labour and Welfare: http://anzeninfo.mhlw.go.jp/index.html)

  • Case of acute organic solvent poisoning during cleaning of degreasing tank with trichloroethylene

    [Location of accident]Trichloroethylene cleaning tank in a factory polishing automotive parts and providing metal surface treatment

    [Cause of accident]A worker who entered the trichloroethylene tank to remove deposits from the inner wall with waste cloth soaked with trichloroethylene was found to have collapsed in a crouching position on the stand in the trichloroethylene tank.

    [Damage/injuries]The worker was rescued immediately and transferred to the hospital. However, he died the next day without regaining consciousness.

    Wearing gas detectors on a routine basis enables early detection of toxic gas leaks and improves work safety.

  • Case of organic solvent poisoning during cleaning of paint film removal/cleaning tank for painting jigs for automotive parts

    [Location of accident]Removal/cleaning tank for painting jigs in an automotive parts manufacturing plant

    [Cause of accident]The victim entered the removal/cleaning tank at around 3:30 pm on the day of the accident to remove paint film sludge.He entered the bottom of the tank and gathered and discharged sediment from the tank. He was poisoned around 4:10 pm after discharging sediment three times.

    [Damage/injuries]When the victim was found, he was found crouching and unconscious in the bottom of the washing tank. He was taken to the hospital by ambulance, treated, and regained consciousness approximately 2 hours and 10 minutes after the incident.

    Wearing gas detectors on a routine basis enables early detection of toxic gas leaks and improves work safety.
